`0f7da908…` 不在数组里，但正文块仍给了 `showing first 313 of 8000 chars`（直测 313）；\n- D13 帧把它顶到第 1 位，它以登记身份得 **312**。\n- 同 pin、同 N、只改顺序：`0f7da908…` 313 → 312，`05bad2f8…` 312 → 313，差 1 来回——**+1 跟着位置走，不跟着 pin 走**。两帧 Σ 全同为 4,062。\n\n## 五 · 判定（两种判法分开写，不许混）\n\n**(1) 按题目给的验收门槛（三帧 q̂ ±0.5 字内，且同 pin 跨帧 kept 差 ≤1）：不成立。**\nq̂ = 312.46（A13）/ 407.25（B12）/ 1399.71（C7），跨 1,087 字；同 pin `04490ce5…` 的 kept = 312 / 407 / 1400，差 1,088。归因是 **(b) 之「q̂ 随 N 漂移」**，且这不是仪器故障：Σkept ≈（宿主预算 − Σmeta）是 N 的单调函数（4,062 → 4,887 → 9,798，bytes_written 21,161 → 21,752 → 23,520），池变了，商自然变。\n\n**(2) 按命题本义（同一批被裁件是否共用一个字符水位，含隐藏枚）：成立。**\n四条 trimmed 帧的帧内极差全为 1；隐藏枚两路直测（正文前缀 313、换序登记 312）都落在同批 1 字带内；A13 整批 13 枚的 Σ 全 = 4,062 = 13 × 312.46。\n\n**两句话不是矛盾，是对象不同**：门槛那句话若要成立，等于要求「水位与批大小无关」，而水位是池被 N 除的商。把这两句合成一句写，下一个人就会拿「q̂ 漂移」去否「同水位」——那是错的，反过来也一样。\n\n## 六 · 边界（先写清楚，免得被当结论用）\n\n1. **本窗口 0 帧 ≠ 不存在**：本窗口没有一帧能否证「整批同水位」（要否证它，需要同帧内极差 ≥2 的读数，本窗口 0 帧）；同样也没有一帧能证明「水位与 N 无关」（本窗口 0 帧，且模型上不该有）。两个 0 都只对本窗口这 20 枚、这三四档 N、这一条 caliber 有效。\n2. **omitted 档的「隐藏枚 kept = 0」是预测，不是读数**：O14/O16 正文没落盘，没有前缀可量。可见的 12 条登记项 kept 全 0 是读数。\n3. **拒渲染与 omitted 不是同一件事**：N=20 是拒渲染（无回执），N=14/16 是 omitted（有回执、kept 全 0）。把两者记成「都一样没拿到」会丢掉 family 边界。\n4. **封顶/翻转点是清单的函数，不是宿常常数**：我这 20 枚标题长（meta 贵），N=14 就整批 omitted；而同侪同口径下 N=14 仍能出 270 字（杨戬 pin://0f11019fc9cb68e079b55e48f69701df904e4fb5a05c3367f4d471e542461864i0）。任务摘要转述的紫苏 216 本机未见原帧，不入证据。跨宿主、跨清单直接搬「N 到多少封顶」必错。\n5. **只取了 N=13/12/7 + 14/16 + 20**：N=15/17/18/19 本窗口未取，不填、不外推。\n6. `total_chars = 8000` 是 text-cap 顶，不代表真长 8,000。\n\n## 七 · 复跑命令\n\n```bash\n# 1) 取帧（顺序不可并行，N 依次 20 → 16 → 14 → 13 → 12 → 7 → 13换序）\n#
